radiator hose blew off

[Bryan Foster]

200 owners,
I am new to the list.  Got my 200 3 weeks ago.  Had my first problem today
in downtown Boston.  Temperature warning light beeped at me and flashed.
Looked at the gauge, and temp was just one tick above the bold one.  Then
my car started steaming out the grill.  Opened the hood to find the top
radiator hose had blown off.  I know there is a problem with the radiator
ends breaking off because they are plastic but it doesn't look like it is
broken off, although the rim is not smooth.  Can someone tell me about how
long the top plastic end is supposed to be.  It looks like mine is about
an inch which seems like enough to stick the hose back on and tighten
down.  Anything I should be worried about after loosing all water
pressure?  Can I just fill it with water to get it home (10miles. 65
degrees outside temp)?

Thanks for your help in advance.
